We haven't picked out our chi yet and are honestly still talking to a few different breeders to find our best 'fit', but we know when we do food is going to be an immediate issue. We have yet to find a breeder down here that doesn't feed Pedigree/Puppy Chow/Beneful or some other cheap grocery store brand. I realize that it is stressful to change the food of a puppy, especially on top of being brought into a new home!
How long should we wait before introducing new food? I worry that such a low quality fare might exacerbate any problems the puppy might experience from stress, but that if we start changing his food right away it might ALSO compound issues.
